In the aftermath of finding Starlight (again) gone wrong, an amnesiac pegasus woke up in a forest filled with mysterious flora and dangerous fauna. Seems like a typical displacement fic, right? No. Actually, after this event, the pegasus will stumble upon a rabbit hole of lost prophesies and history, the involvement of dimensional magic, and the creation (and soon the destruction) of a malevolent entity that will prey on her mind.

And what is its pursuit? Her missing memories, buried deep inside her consciousness, where old wounds might, no, will open. How will she figure sort these out? Why is she here of all pe-ponies that can be displaced, and who exactly is the slightly elusive unicorn in her dreams, Star Order?

Join Comet Pearl in finding the past, fixing present conflict, and saving the future to come.

Key Words: Alternate History, both Equestria and her Home Dimension, although for the latter it’s…a curious and complicated case; amnesia; Tantabus returning? Meh, it’s way worse; Alicorn Involvement; Mind-related battles; Last Arc = The Big Reveal

Part of the Portal-verse in Equus’ side, where her case will not be the only one in a way…Also, the timeline in question takes place after “Castle Sweet Castle”. Tags might change or get added (especially the character slots and the E rating, considering that the memories will become more significant-and...uhh...not for kids?)
Also, the protagonist's name is a giveaway of who she is...but it will take more than that to fully reveal it...

Arcs:
Lost Pearl (Prologue-???)
Light and Darkness (???)
The Star Incident (???)
Oriented (???)
Pearly Times (???)
Welcome Back...Comet Pearl? (???)
Also, this doesn't include the Intermissions that describe various characters from Pearl's home dimension coping with what happened; take note that this is mostly dialogue and mildly tampered with by the Narrator for secret-keeping purposes.
